Accessing 'this' inside the callback should reference my array

im kinda new at javascript so i have an function which is given an array and it filters its elements from the arguments it is passed. What i need though is to make 'this' inside the callback function to refference at my originalArray so that

console.log(this);

would acctually print [1,2,3]. Have in mind that i acctually need to this in these lines because i can only edit all those lines not add some more.
